Alfred James Ewart, FRS[1] (12 February 1872 – 12 September 1937) was an English-Australian botanist.
He had already completed a laborious and useful piece of work, his translation of Wilhelm Pfeffer's treatise on The Physiology of Plants, the first volume of which was published in 1900, the second in 1903, and the third in 1906.
In 1906, Ewart became the foundation chair of botany and plant physiology at the University of Melbourne.
In 1927 Ewart was asked by the government to prepare a new Flora of Victoria which, with some assistance from other scientists, was completed and published in 1930.
Ewart married twice, firstly to Florence Maud Donaldson, a violinist and composer of ability, in 1898 and secondly to Elizabeth Bilton in 1931.
